android - 使用 Maven 对 Android 进行单元测试

Question

我对使用 Maven 构建的 android 项目有疑问，我们让它运行我们的 Activity 测试，但现在我们需要它来运行单元测试。单元测试与 Activity 测试在同一个项目中，我如何在我们的 pom.xml 文件中设置它？

这是父 Pom.xml 文件:

<?xml version="1.0" encoding="UTF-8"?>
<project xmlns="http://maven.apache.org/POM/4.0.0" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
  xsi:schemaLocation="http://maven.apache.org/POM/4.0.0 http://maven.apache.org/maven-v4_0_0.xsd">
  <modelVersion>4.0.0</modelVersion>
  <groupId>andersen.project</groupId>
  <artifactId>Hello-parent</artifactId>
  <version>1.0</version>
  <packaging>pom</packaging>
  <name>Hello - Parent</name>

  <modules>
    <module>HelloWorld</module>
    <module>HelloWorldTest</module>
  </modules>

  <dependencyManagement>
    <dependencies>
      <dependency>
        <groupId>com.google.android</groupId>

        <artifactId>android-test</artifactId>
        <version>2.2.1</version>
        <scope>provided</scope>
      </dependency>
    </dependencies>
  </dependencyManagement>

  <build>
  <sourceDirectory>src</sourceDirectory>
  <testSourceDirectory>test</testSourceDirectory>

这是应用程序 pom.xml:

这是测试pom.xml文件

我应该在父 pom.xml 中添加以下文本吗？:

<dependency>
  <groupId>junit</groupId>
  <artifactId>junit</artifactId>
  <version>4.8.1</version>
  <scope>test</scope>
</dependency>

并将其添加到其他 poms 中？

当我运行 maven 时，输出是:

Junit.framework 不存在

我遇到了同样的问题。这是由父 pom.xml 中的错误配置引起的。您必须删除 dependencyManagement 部分中的范围标记。

像这样:

<dependencyManagement>
  <dependencies>
    <dependency>
      <groupId>com.google.android</groupId>
      <artifactId>android</artifactId>
      <version>2.2.1</version>
    </dependency>
    <dependency>
      <groupId>com.google.android</groupId>
      <artifactId>android-test</artifactId>
      <version>2.2.1</version>
    </dependency>
  </dependencies>
</dependencyManagement>
